Portable booster battery

Abstract: In a tool for boosting (jump starting) a vehicle, it is know that there is a battery as a power source and booster cables to bring the energy to the engine. In this invention, the battery and the cables are incorporated into one unit which includes the battery, the cables and protective holsters (housing) to lodge the cables. The holsters are an integral part of the unit and swivel at 90° (degrees) to permit easy access. In this way, everything can be carried in one hand. Also, because the unit can be easily placed close to the engine, the cables can be much shorter than regular booster cables. It is easier to use since there are only two connections to make instead of four. Finally, the holsters, which house the booster clips protect the user from short circuits.

Description: FIELD OF INVENTION The present invention relates to batteries and more specifically to batteries that are moved from location to location, to connect to different devices, especially discharged or dead batteries of motor vehicles. BACKGROUND OF THE INVENTION Most automobiles are presently powered by an internal combustion engine which must be spun up to speed externally before they can operate. The engines are usually spun up to speed by an electric motor that is powered by a battery. The battery is then charged by a generator connected to the engine once the engine is operating or running. The battery is usually able to store enough charge for the periods that the engine is not running in order to start the engine when needed. When the battery does not have sufficient charge to start the engine, a way must be found to recharge the battery or bypass the battery with a separate charge. Since very often a discharged battery is caused by an external drain such as leaving the lights on or playing the radio, once the engine is started by either recharging the battery or bypassing it by sending a separate charge the automobile will continue to operate properly. Since there are many things that will temporally cause a battery to lose its charge, the need to recharge or bypass batteries with separate charges is common. Very often another or booster battery is brought to the vicinity of the dead battery and electrical cables are used to connect the booster battery to the dead battery in parallel in order to recharge and/or bypass the dead battery. This often known as boosting or jump starting the dead battery or engine. In this method of boosting, the cables are disconnected from the batteries after each use so as to prevent short circuits. This method and structure however, is cumbersome since there are at least two parts and they demand great attention since there are 4 connections to make and a bad connection in either one will result in a short circuit or failure to start the engine. Some manufacturers have tried to resolve the problem by combining the battery and cables in one unit The problems that have arisen with these units are that the cables which are permanently connected to the battery are always live so they have to be protected as to not touch each other. The amount of amperage available in these batteries is very large and if the cables touch each other it would issue a short circuit and damage the cables and batteries. To isolate the live cables, some manufacturers have used protective pouches. These are not practical to use since they are often in the way when trying to boost. Also it is time consuming to put the cables in and out of the pouches. Other manufacturers have incorporated a male cigar lighter plug at the end of the cables permitting the user to plug this into the female cigar lighter plug of the vehicle. The problem with this unit is that one can only use this tool on vehicles equipped with female cigar lighter plugs. Also, since the plugs almost always have a maximum amperage rating of 30 amps and that most starter motors draw much more than 30 amps., the capacity is not adequate. SUMMARY AND OBJECTS OF THE INVENTION It is any object of the present invention to provide a portable booster battery which can be easily carried to a car with a dead battery and connected to the dead battery of the car in order to provide sufficient charge to start the engine. It is also an object of the present invention to make the portable booster battery easy to use, maintain and safe from electrical short circuits which could damage the battery, the cables and the surrounding environment. The present invention achieves these objectives by providing an electrical energy storage device such as a sealed non spillable battery inside a housing. Cables are connected to the terminals of the battery and extend outside the housing. On the ends of these cables are battery or booster clamps which are designed to clamp on and electrically connect to the terminals of the dead battery or any other part of electrical system of the automobile. When the cables and the battery clamps are not being used, the battery clamps can be positioned inside holsters that are connected to the housing. The holsters cover the battery clamps and block the battery clamps from electrically contacting the surrounding environment In this way the clamps are protected when they are not in use, and this prevents electrical short circuits from occurring which would damage property. Inside the holsters is positioned a bit means for connecting with the battery clamp when the clamps are positioned inside the holsters. A groove can also be formed in the housing to retain the cables close to the housing. The entire unit then becomes very compact and easy to transport. A handle can also be provided in the housing. The holsters can be pivotably attached to the housing by a least 90°, in order to make is easier to insert and remove the battery clamps. The holsters each include a cover which is rounded and closed at one end and flat and open at another substantially opposite end. A recharging connection or plug can be connected to the energy storage device and either positioned on the housing or extending from the housing in order to recharge the storage device. In a preferred embodiment, the recharging connection is a male cigar lighter plug which can be plugged into the cigar lighter of an automobile in order to recharge. An accessory connection can also be provided on the housing to electrically connect to accessories such as 12 volt lights, vacuum cleaners and compressors in order to power these devices. This accessory connection is preferably a female cigar lighter. A display means is also preferably connected to the energy storage device and positioned on the housing to display how much charge the energy storage device contains. Another object of the present invention is to provide a unit which is simple in design, rugged in construction, and economical to manufacture.
